According to IEEE 754 Standards, IEEE 754 has 3 basic components
The Sign of Mantissa -
This is as simple as the name. 0 represents a positive number while 1 represents a negative number.
The Biased exponent -
The exponent field needs to represent both positive and negative exponents. A bias is
added to the actual exponent in order to get the stored exponent.
The Normalised Mantissa -
The mantissa is part of a number in scientific notation or a floating-point number, consisting of its significant digits. Here we have only 2 digits, i.e. 0 and 1 . So a normalized mantissa is one with only one 1 to the left of the decimal.
